Precisely why I haven't touched it. Everyone's already "out to get him" and my leaving the band and what appears to be its subsequent dissolution may have already put me on that list. Don't need to do anything else to guarantee a spot there.
From all the descriptions you've written of the guy, if they're even halfway accurate, I wouldn't touch any of his stuff. Finding things in a state other than they left them seems like a sure fire opportunity for a paranoid person to insert a bunch of imagined ominous intent.
